tooltips icon when hovering mouse over pinned applications are disproportionately large. However all icons do not show abnormal behaviour. Pinning and unpinning does not help and problem exists across multiple panels also. also in device notifier, the icons are similarly large and inhibit functionality. This problem started after updating to kde plasma 5.9.4. Using manjaro 17 64 bit kde. Please help me with some solution, i tried everything i could.

I have same issue. Did you resolve it already?

I observed the issue only occured with maia theme (and no other theme, like maia dark even). So i used the maia dark configuration files and maia icons to create a mix and that seems to work fine

Thank you, I will look at it.
Meanwhile I found, there is bug reported about this topic: Bug #380432
